Abstract

Antihypertension action is achieved without diuresis by administration of a thiazide diuretic in an amount which while being sufficient to achieve antihypertension is insufficient to achieve diuresis. Such administration in a non-diuretic amount is effected in 4-8 consecutive hourly doses to achieve reduction of blood pressure without high urine output. The invention further relates to complexes of thiazides with mixed cation-anion exchange resins, to insoluble basic metal hydroxy thiazide salts, the salts of thiazide with calcium disodium edetate or disodium edetate, to molecular complexes of thiazides with long chain polymers such as hydroxy alkyl cellulose polymers, carboxy methyl cellulose and polyvinylpyrrolidone, to beta-adrenergic blocking amine-thiazide salts and to amiloride thiazide salts.
